I guess they want to get into the "Kilowatt club" as well.

Only dual?.. Only quad?.. Only 6?..Torajirou wrote:Good news for the numerous guys who run a Dual Quad-Core Extreme with Quad SLI and 6 hard drives ^^

2 Quad Cores and 4 Graphics-cards and you may attach 6 hard drives.
2 x 100W + 4 x 150w +6 x 10 - 30W = 860 - 980W.
So there is a market even if it is a small one i admit.

I aggree totally, however the real life situation is that ALL PSU's I have ever read a review on all share one thing in common - the efficiency curve, a 1000W PSU that is 80+ certified must hit 80% efficiency at 20% load and upwards, but most PSU's at 10% efficiency are usually pretty lame (low output models to a lesser degree as well).Price aside, buying a PSU that only delivers *just* enough juice is rarely optimal. For silence, we'll want the PSU to run unstrained and cool, and that is partly based on effiency (there are certainly other factors too). If the efficiency of this PSU is better than others at a given watt, then it's worth considering at least, no matter the max watt rating. If peak efficieny is reached at the max load of the system components, why care about the max rating?
There's too much derision on these boards against the high wattage PSUs. No, there're almost no systems that use 1000W, but that's not really the point. Buying a 1000W PSU to power a 1000W system would be stupid. Just like buying a 300W PSU to power a 300W system would be stupid, because it would run hot and noisy. Stressing a PSU is not conducive to silent computing (or anything else)
I have never understood how and why an overclocked rig needs more wattage or indeed a higher PSU overhead than a non-overclocked one - thats just bullshit. An overclocked rig has exactly the same needs as any other PC with one difference - its more sensitive to the power output from the PSU which is exactly why its bullshit.High end rigs probably aren't common amongst posters on this forum, but they certainly exist, and there are quite a lot of heavily overclocked rigs that wouldn't run stable 24/7 on less than a quality 700W PSU.
Hell yeah, but manufacturers will keep on making more powerful PSU's, how long will it be before there is a 3,000W PSU.!Fortunately it looks like the die shrinks of the latest chips reduce overall power consumption even though they perform better. I hope that trend continues.
Yes of course the entire range, from idle to max load, has to be looked at when considering efficiency of the PSU.andyb wrote:If a PC's peak load is 300W and its nominal desktop power usage is 100W, then that 1,000W PSU is going to spend most of its time (desktop) wasting power and creating more heat than is necessary - and will usually be noisier because of that.

The truth of the matter comes down to the quality of the PSU and the quality of its power output, a shit 1,000W PSU is still a shit PSU, but if that system was given a very good 500W PSU it might just be a bit more stable on an overclocked system, whereas that shit 1,000W PSU might be fine on that non-overclocked system that is only using 100W on the desktop.
I actually really doubt that. I think we might see up to 2000W (we already have for that matter), but I get the feeling that manufacturers more and more start competing on efficiency, noise, ripple and features like modular cabling and software to control and monitor the PSU. PC power consumption has reached a plateau, and I think it'll go slightly down from here on out, if anything.andyb wrote:Hell yeah, but manufacturers will keep on making more powerful PSU's, how long will it be before there is a 3,000W PSU.!

If newbie x reads on a forum that he needs an 850 watt or higher psu for his new system, he may believe it. X goes to the store and corsair only has a 620. Well, he is more inclined to buy junkie 1000 watt than corsair. Corsair has lost on a sale.
I aggree also, I wasnt blaming corsair or any other companies, merely marketing people. And to be fair I cant blame them either, they market what can be sold, so again this comes full circle to the people who actually sell the stuff and the reviewers who promotoe the stuff often without saying what system your "actually" need to be able to use half of its power output.gforcefan wrote:

I should have said that a bit clearer, what I meant is system (a) uses 500W, system (b) uses 300W, system (c) uses 400W, which one is overclocked.??? The overclocking doesnt matter at all, its the "actual" peak power usage that matters.As for overclocking, it most certainly increases power consumption. Heavily overclocked rigs can draw an extra 50%+ power, compared to stock values. That's partly because OCers increase the voltage to make the overclock stable. That goes for GPU, CPU, FSP/NB, etc.
This is a large part of it honestly. Customers are buying 1000W PSUs. Our distributors and vendors want us to make a 1000W PSU because our other PSUs are selling very well. It makes sense to make one.gforcefan wrote:I don't blame corsair, but dumb users and "experts" who don't know what they are talking about.

The ripple specs on that one are insane... I wonder if CWT isn't pushing that platform a bit too far.

Hmm... JonnyGuru didn't seem to have any that problem. 5V rail was excellent, 3.3V rail dropped to 3.19V when loaded up but no lower.Oleg Artamonov wrote:Ripple under full loadOklahoma Wolf wrote:The ripple specs on that one are insane... I wonder if CWT isn't pushing that platform a bit too far.
Cross-loading graph
Ripple is almost ok, but voltage stability is too bad, and 1200 W model (based on the same design) is even worse.
